Commander type 1911a1 .45s......
I'm partial to the CCW size 1911a1 SAO(single action only) models too.
I like the rounded or "bobtail" type frames-grip areas.
I'm a bit "large" & dislike the rough, sharp or pointy edges of some 1911s.
I agree with what author & tactics trainer; Massad Ayoob said(quoting gunsmith Ikey Sparks); "A carry gun should feel like a well used bar of soap."
As for brands, Id check Kimber-USA, Para-USA, S&W, SIG Sauer, Ruger, Kahr Arms/Auto Ord, Ed Brown, Les Baer, Wilson Combat, Colt.
The Smith and Wesson E series 1911 is nice. The Clapp Colt Commander .45acp is a sweet pistol. The SIG Commander sizes are well engineered.
A local gun shop near me is doing it's own SIG 1911a1 .45acp deal; buy a .45acp & get a
free SIG Mosiquito .22LR semi auto pistol.
Custom shops like Ed Brown, Les Baer, Wilson Combat etc are not cheap but you get a high quality 1911a1 carry gun.
Another choice which isn't a 1911 but does fit the same size is a SIG Sauer P220 Carry .45acp SAO. It's a P220 but has a single action only design.
